SPECIFICATION forming part of Letters Patent No. 371,668. dated October18, 18g?.

Application tiled March 28, 1887. Serial No. 32f65. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN M. MAELIN, of New' Haven, in the county of NewHaven and State of Connecticut, have invented a certain 5 new and usefulImprovement in Revolving Fire-Arms, of which the following is aspecitication.

My invention relates to revolving firearms; and it consists in certainnew and useful conro strnctions and combinations o f the parts of thesame, substantiallyl as hereinafter described and claimed. t'

In the drawings, Figure 1 is a top plan view of aportion of a revolvinglire-arm constructed x5 according to my invention. Fig. 2 is a sideelevation of the same, with the cylinder in section, and breechplate.Fig. 3 is a side view of the bolt or latch used to lock the barrel tothe frame. Fig. 4 is a lower` face viewv zo of the same. Fig. 5 is abottom face view of the pivoted lever used to slide the bolt. Fig. 6 isan edge view of the same. Fig. 7 isa top view of the sliding cover usedto confine the other parts in position. Fig. S is an edge z 5 view ofthe same.

B is the barrel of the arm, which has a rearward extension, b, over thecylinder, to lock it to the frame.

C is the revolving cylinder, mounted on The barrel B has on its lowerside a projection, through which is the transverse hole d,

forming a pivot-bearing, by which it is pivoted to the frame in theusual manner.

35 Through the extension b, near itsrear end, thevertical mortiseb' ismade, which receives the projection or stud b2 of the frame through itwhen the barrel is locked to the frame. The breech-plate b3 is attachedto the frame 4o behind the cylinder.

The lock and handle are of the ordinary construction, and are not shown,'as their application will be readily understood.'A Y The bolt or latche is placed in a longitudi- 45 nal chamber formed in the upper side ofthe extension b, forward of the mortise b', and the bolt is made shorterthan this chamber, so as to be capable of sliding endwise therein. Thisbolt has a transverse slot, e', in its lower side, formed widest at theend farthest off, in Fig. 8. A flat bar or lever, d', is made with thethicker or shouldered projection d2 on its upposition.

per side at one end and the head d3 pivotcd upon its other end. .Theshoulders between,- the thicker end portion of lever d. and main 5fpart. are-vertical to its face and rounded horizontally, as shown bydotted lines in' Figs. 1 and 5. This lever is narrow enoughhorizontallyto be received in slot e of bolt e and to just lill thenarrow end of said slot when it 6( lies therein against the diagonalside thereof, as shown by dotted lines in Fig. 1`. A transverse slot iscut through the nearer wall, Fig. 4 2, of the chamber in extension b,considerably wider horizontally than lever d' and `wide 6 enoughvertically to allow the thicker portion 1,r2 of the lever to passthrough'it,.and opposite to this slot, through the opposite wall, (shownin the upper side of Fig. 1,) another slot is cut, of the same widthhorizontally at its outer end 7 as the end of the lever d', and growingwider on the rear sideas it goes inward, and ol' the proper depth toreceive the thick end d2 of the lever. These opposite slots, whichreceive the lever d',` are also so formedfthat theirfront vertical wallsare in the'sarne plane, at right angles to the extension b, and theirrear ver-V tical walls are in the same plane and at an acute angle tothe longitudinal axis of said extension, thereby forming atransversechami ber for the reception of the lever, the narrow end of which formsits fulcrum,gan d within the other parts of which it can swinghorizontally upon said fulcrumas a center, substantially as shown bydotted lines in Fig. 1. A 1 spiral spring, s, is placed in the chamberwhich receives the bolt or latch e, between the front end of the latchand the front end ofthe chamber, to hold the bolt or latch. in. itsbackward A cover, m, is also provided to inl close the latch e' in itschamber. -This cover has tongues m m on its end and sides, which t intoslots'made in the walls of the chamber of bolt e, as shown by dottedlines in Figs. 1 and2.' 'y

To place the several parts in working` adj ustment I first insert thelever d in its trans- -verse slots with its end projection, d,uppermost. I then place the bolt or latch e in its chamber with its slote downward and embracing the lever d', and place the spring s inposition ahead of its forward end, and, lastly, drop the cover m on topof the bolt with the side tongues, mm, in the mortise b', and slide itforward into place, its tongues m m entering their slots in so doing. Itwill now be evident lthat by pressing against the head d3 of lever d thebolt or latch e may be drawn forward in its chamber and unlock theextension b from the stud d2, and that the bolt or latch willautomatically lock into the stud whe the extension and stud arebroughttogether. The lever d is confined in its place by the enlargementdz upon its end, which`engages behind theside of the bolt e above itsslot e and pre- Vents the escape of the lever, and the pressure of thespring s upon the bolt and lever willv always keep the dat: face of thepivotedhead d3 of the lever against the face of the extensionb andexclude dirt, &c., from the slot of the lever at its widest end. By the.pressure of the thumb behind the pivoted head d3 it will be keptagainst this face of the extension asit nieves forward, and the slot ofthe lever will always be kept covered, the lever moving endwise throughits chamber to allow of this. By

this construction I obtain the advantages of 'a directsliding cross-barin moving the bolt or latch e forward with the greater power and freeraction of the lever, together with simplicity and durability inconstruction.

What I claim as new and of my invention 1s- 1. The combination of thebarrel-extension b, the frame-stud b, the sliding bolt e, providedwithslot e', and the lever d', pivoted in one side ofthe extension, passingthrough said slot and projecting beyond said extension upon theopposite-side thereof, substantially as de scribed.

2. The combination of the barrel-extension b, the frame-stud b2, thesliding bolt e, provided With slot e', the spring a, and the lever d',pivoted in one side of the extension, passing throughsaid slot andprojecting beyond said extension upon the opposite'side thereof,-

" substantial] y as described.v

in one side of the extension and projecting beyond the other a'ndpassing through said slot,

and provided with enlargement di, locking it behind bolt e,substantially as described.

4. The combination of the barrel-extension b, the frame-stud b2, thesliding bolt e, provided with. slot e', the lever d', pivoted in oneside of the extension and projecting beyond the other and passingthrough said slot, and the head di, pivoted upon the projecting end ofthe lever, substantially as described.

5. The combination of the barrel-extension b, the frame-stud b, thesliding bolt e, provided with slot e', the lever d', pivotedin one sideof the extension upon a fulcrum, upon which it is adapted to both swinglaterally and slide longitudinally, and projectingbeyond the other faceof Said extension, and the head d", attached to the said projecting endof said le ver and bearing upon said other face, substau tially asdescribed.

6. The combination of the barreLeXtension b, the frame-stud b2, thesliding bolt e, provvided with slot e', wider at one end than at -theother, the lever d', located in a slot pass- JOHN M. MARIAN. y
